Hourly Rate Calculator
Work backward from the yearly income you want: business costs and a tax set-aside spread over the hours you can actually bill, so your rate has a floor.
Invoice Due Date Calculator
The exact due date for Net 7/10/15/30/45/60/90 terms from any invoice date — calendar days, weekends included, with the ready-to-print terms line.
Late Fee Calculator
What an unpaid invoice costs the client each month it sits past due — simple interest, no compounding — plus the policy line to print on every invoice.
Why these three
Most payment trouble on small jobs traces back to one of these numbers being a guess. A rate pulled from a competitor's truck door doesn't cover your slow weeks. "Net 30" written without a date gets paid whenever. And an invoice with no late-fee line has no cost attached to sitting in the pile. Each tool computes one of them in a few seconds, client-side, with nothing sent to a server.
When the invoice itself needs writing, the complete invoice-writing guide covers every field in order, and voice invoicing is how Voice Invoice fills them from a 60-second recording.
